Flying fish roe is an optional but
nice touch -- look for it in specialty Japanese food
shops. If you're so inclined, you can make this with real
crab rather than the fake stuff ... but it'll be quite a bit
more expensive.

1. Peel and slice the avocado
into thin strips. Cut the crab sticks in half.2. Lay a bamboo rolling mat on a
flat work surface. Place a sheet of saran wrap on top. ( need help
with the technique? )3. Place 1/2 sheet of nori on the mat. Smooth a thin layer
of rice to cover the sheet Wet fingers in vinegared water to smooth on the
rice evenly. Flip the rice and nori (the nori should now be facing up.4. Lay a strip or two of avocado and a
strip of crab in the middle of the nori. Roll sushi, taking care not to
let the ingredients slide around or the nori to skew.5. Repeat with remaining
ingredients. 6. Spread the flying fish roe, if
you're using it, in a large plate. Turn each roll carefully in the
plate, covering the rice with the roe. 7. When you've finished making the rolls, cut each roll into
3/4" thick slices. Serve.
